The same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code. Andrzej Wojcicki/Science Photo Library via Getty Images Nearly all life, from bacteria ...

UC Berkeley scientists discovered that a microbe can interpret the UAG stop codon in two ways, producing different proteins ...

All living things on Earth use a version of the same genetic code. Every cell makes proteins using the same 20 amino acids. Ribosomes, the protein-making machinery within cells, read the genetic code ...

In the largest screen to date for alternative genetic codes, a computer program named Codetta scanned more than 250,000 genome sequences from bacteria and archaea to identify five never-before-seen ...

The genetic code is a set of rules defining how the four-letter code of DNA is translated into the 20-letter code of amino acids, which are the building blocks of proteins. The genetic code is a set ...

Despite awe-inspiring diversity, nearly every lifeform—from bacteria to blue whales—shares the same genetic code. How and when this code came about has been the subject of much scientific controversy.

Researchers have reconstructed a long string of genetic code for what they believe is the common ancestor of placental mammals — a shrewlike creature that lived in Asia more than 75 million years ago.

A surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...

RALEIGH – In a new study, North Carolina State University researchers characterize a range of molecular tools to rewrite – not just edit – large chunks of an organism’s DNA, based on CRISPR-Cas ...

Research suggests that we may have only begun to scratch the surface on the number of variations present in the genetic codes of all living organisms. Crack open a biology textbook and you will find a ...
